I get pretty much the same message from dvd decrypter when I try to burn anything..
Nothing I do helps.. MY drive is the Pioneer A07, this thing will however read true pressed DVD's and CD's but not any burnt media..I cannot figure it out. I have done everything from reinstall hardware/software etc..
I did upgrade from FW 1.20 to 1.21 and it did accept the update but no change..

Im still at a loss... I am about to go nuts... I have put the 107 in a different machine and same result... So I guess the damn drive is toast... after 7mths pretty ridiculous.... Gonna have to send it to Pioneer I guess...
